I guess we'll see whether the 'double' claim holds up in practice, but there seems to be good potential in this idea-

"According to a new paper released at the IEEE Semi-Therm conference, IBM has discovered a way to dramatically improve processor cooling. Unlike some other recent cooling breakthroughs, IBM's discovery appears to be one that should be relatively inexpensive to implement, and could have a significant impact on consumer microprocessors in the near future. Without fundamentally changing the approach to CPU cooling today and without the use of more advanced setups like water coolers, IBM says that they can double CPU cooling capacity while making it easier and safer to do so.
